# Changelog
## 0.2.0 — runtime composition repair
### Root cause fixed
The 0.1.x runtime did not consume the example gallery. `prompt.py` emitted only a generic node/edge scaffold, the agent skill did not require reference inspection, VizSpec had no composition grammar, `layout.py` always used one topological layout, and the SVG renderer always drew the same rounded-card vocabulary with a visible title/question/footer. The linter also allowed several unconnected nodes.
Changing only `examples/` therefore could not change generated output. A model could produce 25 differently labelled specs that all compiled to the same picture.
### Added
- VizSpec 1.1 `composition` block.
- Ten composition profiles and node/edge semantic roles.
- Context-sensitive reference selection with scores, matched terms, preview paths, and executable runtime-spec paths.
- Context/profile compatibility lint.
- Hard rejection of disconnected cards and excessive isolated nodes.
- Profile-specific structural gates.
- Profile-specific deterministic compositors.
- Diagram-only SVG output with hidden accessibility metadata only.
- Ten executable runtime profile fixtures.
- `techviz audit-batch` label-independent topology-collapse detection.
- Batch-collapse, context-profile, runtime-profile, and diagram-only tests.
### Changed
- `techviz prepare` records `visual_reference_candidates` in the context package.
- `techviz prompt` embeds selected reference grammars and restricts the candidate profile set.
- `techviz references` prints score, matched terms, preview, and runtime-spec paths.
- Manifests record composition profile, reference ids, and diagram-only status.
- Agent instructions require reference inspection and batch audit.
### Compatibility
VizSpec 1.0 can still be parsed using the compatibility layout, but it emits a warning. New work should use VizSpec 1.1. Existing 1.0 specs must be upgraded to obtain profile-specific output and context-selection gates.
